[ESP/TCS/ABS]
C1114 ACTUATOR RELAY SYSTEM
YES
>> GO TO 3.
NO
>> Repair or replace malfunctioning components.
3.
ABS POWER SUPPLY CHECK (UNDER LOAD CONDITION)
Use 12V lamp (normal rating 10 to 20W) connected between E36 terminals 1 and 3. With ignition switch ON
check bulb illuminates correctly.
Is the inspection result normal?
YES
>> GO TO 4.
NO
>> Check both power supply and ground circuit.
4.
CHECK ABS ACTUATOR AND ELECTRIC UNIT (CONTROL UNIT) GROUND CIRCUIT
1.
Turn ignition switch OFF.
2.
Disconnect ABS actuator and electric unit (control unit) connector.
3.
Check continuity between ABS actuator and electric unit (control unit) harness connector terminals and
ground.
Is the inspection result normal?
YES
>> Replace ABS actuator and electric unit (control unit).
NO
>> Repair or replace malfunctioning components. (Check ABS each bolt for tightness and corrosion.)

CHECK ACTIVE TEST
1.
On “ACTIVE TEST”, select “ABS MOTOR”.
2.
Touch ON and OFF on screen. Make sure motor relay and actuator relay operates as shown in table
below.
NOTE:
A brief moment of ON/OFF condition occurs every 20 seconds after ignition switch turned ON. This is not malfunction because it is
an operation for checking.
Is the inspection result normal?
YES
>> INSPECTION END
NO
>> Go to diagnosis procedure. Refer to

C1115 WHEEL SENSOR
Description
INFOID:0000000000977406
When the sensor rotor rotates, the magnetic field changes. The sensor converts the magnetic field changes to
current signals (rectangular wave) and transmits them to the ABS actuator and electric unit (control unit).

Diagnosis Procedure
INFOID:0000000000977407
CAUTION:
Do not check between wheel sensor terminals.
INSPECTION PROCEDURE
1.
CHECK SENSOR AND SENSOR ROTOR
• Check sensor rotor for damage.
• Check wheel sensor for damage, disconnection or looseness.
Are the sensor and sensor rotor normal?
YES
>> GO TO 2.
NO
>> Repair wheel sensor mount or replace sensor rotor. Then perform the self-diagnosis.
2.
CHECK CONNECTOR
1.
Turn ignition switch OFF.
2.
Disconnect ABS actuator and electric unit (control unit) connector.
3.
Disconnect malfunctioning wheel sensor connector.
4.
Check terminal for deformation, disconnection, looseness, and so on. If any malfunction is found, repair or
replace terminal.
5.
Reconnect connectors and then perform the self-diagnosis. Refer to
.
Is any item indicated on the self-diagnosis display?
YES
>> GO TO 3.
NO
>> Poor connection of connector terminal. Repair or replace connector.
3.
CHECK WHEEL SENSOR HARNESS
1.
Turn ignition switch OFF.
2.
Disconnect ABS actuator and electric unit (control unit) connector.
3.
Disconnect malfunctioning wheel sensor connector.

ABS SENSOR
[ABNORMAL SIGNAL]
Miss-match between the 4 wheel speed sensor signals.
• Harness or connector is not a
possible cause
• Other possible causes
- Tire radius (due to wrong size
or pressure) interference.

Measurement terminal for ground circuit
5.
Reconnect ABS actuator and electric unit (control unit) connector.
Is the inspection result normal?
YES
>> GO TO 4.
NO
>> Repair or replace malfunctioning components.
4.
CHECK WHEEL SENSOR POWER SUPPLY CIRCUIT
1.
Turn ignition switch ON.
2.
Check voltage between wheel sensor harness connector power supply terminal and ground.
Is the inspection result normal?
YES
>> Replace applicable wheel sensor.
NO
>> Replace ABS actuator and electric unit (control unit).
